[jira] Updated: (SOLR-687) unlockOnStartup unsafe for multicore

     [ https://issues.apache.org/jira/browse/SOLR-687?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yonik Seeley updated SOLR-687:
------------------------------

    Attachment: SOLR-687.patch

Here's a patch that keeps track of what directories it's seen before, and only performs unlock the first time on each one.  I think this more correctly reflects the original unlockOnStartup semantics.
